This is a longitudinal study of an intervention in 14-18 adolescents intended to increase the frequency of condom protected sex. Subjects were allocated randomly to treatment or control groups. All were evaluated prior to the intervention, immediately after the intervention, 6 months and 12 months after the intervention.The outcome variable is the logarithm-transformed frequency of condom-protected sex ( log(Y+1) )."
